Chemical Structure

3-Methylcycloheptanone CAS 933-17-5 chemical structure

Description

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

3-Methylcycloheptanone (CAS 933-17-5) is a high-purity analytical reference standard with the molecular formula C8H14O and a molecular weight of 126.20 g/mol.

Owing to a hydroxyl group, an ether linkage, 3-Methylcycloheptanone is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 126.20 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
